CVE Vulnerability Catalog

The AWP Classifieds WordPress plugin before 4.4.9 does not validate the type of files extracted from an uploaded ZIP archive during its listing-import feature. This allows users with the plugin's management capability to upload arbitrary PHP files to a publicly accessible, network-shared directory and achieve remote code execution.

Backdrop CMS 1.34 before 1.34.5 and 1.35 before 1.35.1 doesn't sufficiently protect configuration exports when delivering a compressed archive. This vulnerability is mitigated by the fact that an export must have been previously requested by someone with the "Synchronize, import, and export configuration" permission. NOTE: CVE-2026-107914 refers to the vulnerability in which config.admin.inc does not ensure that a file_unmanaged_delete operation occurs, so many archives could persist.

A type confusion vulnerability in the _read_flags function (src/commands/cmd_dispatcher.c) in FalkorDB before 4.20.0 allows a remote authenticated attacker who can run GRAPH.QUERY to cause a denial of service and possibly disclose or corrupt memory. The function accepts a --bolt argument from any client and casts the following command argument, a Redis string object, to a Bolt client structure without checking its origin; the result-set code then dereferences pointers read from that object. The argument is parsed even when the Bolt endpoint is disabled, so default configurations are affected.

An improper authentication vulnerability in the is_authenticated function (src/bolt/bolt_api.c) in FalkorDB before 4.20.0 allows a remote unauthenticated attacker to execute graph queries without credentials through the Bolt endpoint. The function decides whether a password is required by issuing an empty AUTH command to Redis and treats only a WRONGPASS error as meaning that a password is required; any other error, such as LOADING while a dataset is being loaded, MASTERDOWN during replication failover, or OOM under memory pressure, causes the client to be treated as authenticated. Only deployments that enable the Bolt endpoint (BOLT_PORT, disabled by default) are affected.

A stack-based buffer overflow in the _RdbLoadEntity function of the RDB graph decoders in FalkorDB before 4.18.4. A remote attacker who can issue Redis replication commands can send a crafted RDB stream with an attacker-controlled entity property count. The count sizes two variable-length arrays on the thread stack with no upper bound, and the decoder then fills them with attacker-supplied values.

HTTP/2 servers can crash due to concurrent modification of the HPACK encoder without synchronization. Two goroutines modify the encoder: one encodes a HEADERS frame, the other changes table size when handling a SETTINGS frame with SETTINGS_HEADER_TABLE_SIZE. A malicious client can repeatedly send requests while changing the header table size to crash the server.

Multiple ECH outer extension references are not permitted under RFC 9849. Previously, a client could send a crafted packet with multiple references, causing memory exhaustion. Now such packets are rejected as malformed, curbing the memory amplification vector.

Previously, a user operating inside a malicious Go project that defines a bogus golang.org/toolchain go.sum entry and operates a malicious GOMODPROXY could bypass the intended checksum. It is now ensured that golang.org/toolchain always goes to the network for the canonical checksum.

Previously, a user operating inside a malicious Go project that defines a bogus golang.org/fips140 and operates a malicious GOMODPROXY could serve an arbitrary module in its place. The trusted ziphash for the bundled golang.org/fips140 module is now unpacked and its entry in GOMODCACHE is constructed so it can be verified by the toolchain.

Parsing a multipart form can bypass memory limits and read an arbitrarily long line into memory when the remaining limit at the start of a part is less than 400 bytes.

When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to CONNECT converts the connection into a tunnel, the server should not treat it as continuing to contain HTTP.

Missing authorization in Azure Event Grid allows an authorized attacker to perform spoofing over a network.

Exposure of sensitive information to an unauthorized actor in Azure API Center allows an unauthorized attacker to disclose information over a network.

A malicious HTTP/2 peer can cause excessive CPU consumption in the client or server by opening a large number of streams and then sending many small SETTINGS frames containing SETTINGS_INITIAL_WINDOW_SIZE values.

When parsing a Range header containing a large number of small ranges, FileServer(FS), ServeContent, and ServeFile(FS) can consume an excessive amount of CPU.

Historically, the HTTP/2 implementation has been rather lax about malformed framing-related headers, as they cannot interfere with HTTP/2 framing. However, this makes it possible to forward responses containing such headers to an HTTP/1 client when acting as a reverse proxy. If the HTTP/1 client also does not behave strictly enough, this can result in response smuggling.

When "Trailer" headers are sent by a client, the HTTP server internally uses the header values to populate the Request.Trailer map passed to the server handler. Because Request.Trailer is a map, each entry incurs memory overhead. For HTTP/2 servers, a malicious client can exploit this by sending a "Trailer" header that declares a large number of fields, causing the server to allocate a disproportionate amount of memory while bypassing Server.MaxHeaderValueCount and Server.MaxHeaderBytes limits.

When http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, it writes the body directly to the connection without framing after the request headers. If the server rejects the CONNECT request with a non-2xx keep-alive response, Transport returns the connection to the idle pool. Because CONNECT requests do not have a request body, the server may interpret the trailing body bytes as a subsequent pipelined HTTP/1.1 request on the connection, leaving the pooled connection desynchronized and causing the next caller that reuses it to read the response to the injected request.

SumatraPDF 3.6.1 and earlier embeds selected or pasted translation text in quoted Windows command lines in src/SelectionTranslate.cpp using incomplete quote-only escaping. The affected BuildGrokTranslateCmdLineTemp(), BuildClaudeTranslateCmdLineTemp(), and BuildCodexTranslateCmdLineTemp() functions can allow attacker-controlled text to inject model, working-directory, approval, or sandbox-bypass flags when the corresponding agentic CLI backend is installed and used.

SumatraPDF 3.5.2 and earlier substitutes an attacker-controlled SyncTeX source filename for the %f placeholder in an external editor command line without safe Windows argument quoting, and the resulting command line is passed to CreateProcessW(). A user with an external editor configured or auto-detected who opens a PDF with a crafted .synctex.gz file and invokes inverse search can inject command-line flags.
